A sexual position developed in the opium dens of south china, the Reverse Polish Cowgirl is performed by both participants laying side by side, and thensex spontaneously occurring to their immediate right. Not to be confused with Reverse Polish Notation, this sexual position has only ever been performed twice, both times by Sunny and Cher, the second such instance involving a crocodile and a tub of butter.

Hey Cher! Still alien-esque-ly thin I see! Looks like there's been too much Reverse Polish Cowgirl in your life!
